Description

Technical Field

[0001] This invention relates to the technical field of loading equipment for transporting or storing reinforcing cages, and specifically to an adjustable positioning device for storing and transporting reinforcing cages for pile foundations and piers. Background Technology

[0002] Traditionally, the storage and transportation of steel cages for pile foundations and piers involves fabrication in an indoor steel processing yard followed by hoisting from the storage area to a flatbed truck using a gantry crane. To prevent the steel cages from falling off the truck during transport, railings are installed on both sides of the truck bed. However, the spacing between these railings is often greater than the diameter of the steel cage. Furthermore, steel cages of different diameters are not fitted with clamps for each diameter. Transport personnel simply place wooden blocks on both sides of the steel cage to secure it. This can lead to quality issues such as deformation of the steel cage due to compression between the cage and the wooden blocks during turns, and even the safety hazard of tilting and rolling off. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention proposes an adjustable positioning device for storing and transporting steel cages for pile foundations and piers, which has the advantages of strong loading stability, applicability to steel cages of different sizes, and high safety.

[0004] The technical solution of this invention is implemented as follows: An adjustable positioning device for storing and transporting steel cages for pile foundations and piers includes a bottom beam, a support beam, a rope support, and a support structure. The support structure includes a rope loop, a cable, a rope groove, and a support rod. The top surface of the bottom beam is provided with a sliding groove. Multiple support beams are provided along the length of the bottom beam. A steel cage placement area is formed between two adjacent support beams, and the bottom end of the support beam is slidably disposed in the sliding groove. The rope groove is located at the top of the rope support and has a semi-circular structure. Rope loops are provided on both sides of the rope groove, through which the cable passes. A rope pressure plate is provided at the top of the rope groove to press the cable downwards. Both ends of the cable are fixed to the side surfaces of the support beams located on both sides. The inner bottom wall of the sliding groove is evenly provided with toothed grooves, and the support beam is provided with a lifting rod. The bottom end of the lifting rod is fixedly installed with a toothed block for engaging the toothed groove. The first end of the rope loop is slidably connected to the rope support, and the sliding trajectory of the rope loop is a circular trajectory with the center of the rope groove as the circle. The second end of the rope loop is suspended in the air. The top end of the support rod is rotatably connected to the second end of the rope loop, and the bottom end of the support rod is rotatably connected to the lifting rod. The support beam is equipped with an upward pull spring, and the bottom end of the upward pull spring is connected to the lifting rod. It is used to pull the lifting rod to the highest position so that the tooth block separates from the tooth groove and the rope loop is in a horizontal state. When the steel cage is placed in the steel cage placement area, the rope loop is squeezed by the steel cage into a state with the second end facing down and the tooth block bites into the tooth groove.

[0005] Furthermore, a rope-pressing bolt is rotatably installed on the top of the rope pressure plate, and the rope-pressing bolt is threaded onto the rope support. A sliding block is fixedly installed at the bottom end of the support beam. The sliding block is slidably installed in the sliding groove, and a lifting groove that passes through the support beam is opened from the bottom end of the sliding block upwards. The lifting rod, tooth block, and pull spring are all installed in the lifting groove.

[0006] Furthermore, the rope loop has a notch on one side facing the reinforcing cage, and the cable is exposed through the notch. The side of the rope loop opposite to the notch is flat. When the rope loop is in a state where the second end is vertically downward, the side of the rope loop opposite to the notch contacts the side of the supporting beam.

[0007] Furthermore, arc-shaped grooves are provided on the inner walls of both sides of the rope groove, and arc-shaped sliders are provided on both sides of the first end of the rope sleeve. When the rope sleeves on both sides of the rope groove are in a horizontal state, the opposite ends of the arc-shaped sliders on the two rope sleeves are in contact.

[0008] Furthermore, arc-shaped guide rails are fixedly installed at both the front and rear ends of the rope support. Arc-shaped guide blocks are slidably arranged on both the left and right sides of the arc-shaped guide rails. A toothed sleeve is fixedly installed on one side of the arc-shaped guide block. A side pressure rod is fixedly installed on the outer end of the toothed sleeve. A ratchet is slidably inserted into the inner end of the toothed sleeve. An internal pressure spring is connected between the inner top wall of the toothed sleeve and the top of the ratchet. Incomplete ratchet wheels are provided on both the front and rear sides of the rope support, and the teeth on both sides of the incomplete ratchet wheels face opposite directions. Two side pressure rods located on the same side in the left and right directions of the rope support are fixedly connected by a synchronizing rod. A liftable elastic telescopic rod is connected to the toothed sleeve. When the rebar cage is placed in the rebar cage placement area, the elastic telescopic rod applies a downward pulling force to the rope sleeve. When the rebar cage placement area is in an idle state, the elastic telescopic rod is in a free length state and the side pressure rod is in a vertical upward state outside the rebar cage placement area.

[0009] Furthermore, the ratchet contacts the side opposite to the rope support, a lifting bolt is rotatably connected to the top of the ratchet, a threaded sleeve is fixedly installed on the surface of the rope support above the ratchet, and the lifting bolt is threadedly connected inside the threaded sleeve. When the top of the ratchet contacts the bottom of the threaded sleeve, the ratchet is engaged with the incomplete ratchet.

[0010] Furthermore, both the front and rear surfaces of the lifting rod are fixedly connected to an "L"-shaped connecting plate, the top of the connecting plate is fixedly connected to a lifting plate, and the bottom ends of two elastic telescopic rods located on the same side in the front and rear directions are respectively rotatably connected to the two ends of the lifting plate. The top ends of the elastic telescopic rods are rotatably connected to the arc-shaped guide block. Both the front and rear surfaces of the rope support are provided with through grooves for the lifting of the connecting plate.

[0011] Furthermore, the front and rear surfaces of the rope support are respectively provided with a spaced arrangement between them and the corresponding arc-shaped guide rails to form a receiving area. The toothed sleeve is located in the receiving area and is in contact with the opposite side of the rope support.

[0012] Furthermore, the length of the cable between the opposite ends of the rope loops on both sides of the placement area is less than half the circumference of the steel cage, and the length of the cable between the opposite ends of the rope loops on both sides of the placement area is greater than half the circumference of the steel cage.

[0013] Furthermore, the support structure has a pair of cables arranged in a front-to-back pattern on the rope bracket, and the distance between the centers of the two cables is greater than the width of the top opening of the sliding groove.

[0014] The present invention has the following beneficial effects: 1. By sliding the support beams onto the bottom beams and setting cables as the structure to support the steel cages, and by setting the cable length of the steel cage storage area to be adjustable, this invention can be applied to the storage of steel cages of different sizes. When storing the steel cages, the support beams on both sides of the steel cage storage area can clamp the steel cages from both sides, which greatly improves the stability and safety of the steel cage storage.

[0015] 2. By setting up a rope loop and using the support rod and lifting rod in conjunction, the weight of the steel cage itself can be used to control the engagement of the toothed blocks and toothed grooves to position the support beam, thereby clamping and positioning the steel cage. This process is achieved directly by lowering the steel cage without manual operation, making it more convenient to use.

[0016] 3. By setting up side pressure bars, the steel cage is subject to multiple circumferential limiting effects when it is stored, which greatly improves the stability of the steel cage. Moreover, the purpose of the side pressure bars to achieve side pressure on the steel cage is to be automatically achieved during the lowering process of the steel cage, which is convenient to use.

Detailed Implementation

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 16 As shown, the present invention provides an adjustable positioning device for storing and transporting steel cages for pile foundations and piers, comprising a bottom beam 1, a support beam 2, a rope support 3, and a support structure. The support structure includes a rope loop 4, a safety anchor, a rope groove 6, and a support rod 7. Please refer to [link / reference needed]. Figure 16 As shown, a sliding groove 8 is provided on the top surface of the bottom beam 1, and multiple support beams 2 are provided along the length of the bottom beam 1. A steel cage placement area is formed between two adjacent support beams 2, and the bottom end of the support beam 2 is slidably placed in the sliding groove 8. Please see Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the rope groove 6 is located on the top of the rope support 3, and the rope groove 6 has a semi-circular structure. Rope loops 4 are provided on both sides of the rope groove 6. The cable 5 passes through the rope loops 4 and the rope groove 6. A rope pressure plate 9 is provided on the top of the rope groove 6 to press the cable 5 downwards. Both ends of the cable 5 are fixed to the side surfaces of the support beams 2 located on both sides. Please see Figure 10 , Figure 11 and Figure 16 As shown, the inner bottom wall of the sliding groove 8 is evenly provided with toothed grooves 10, and the support beam 2 is provided with a lifting rod 11. The bottom end of the lifting rod 11 is fixedly installed with a toothed block 12 for engaging the toothed grooves 10. Please see Figure 10 and Figure 12 As shown, the first end of the rope loop 4 is slidably connected to the rope support 3, and the sliding trajectory of the rope loop 4 is a circular trajectory with the center of the rope groove 6 as the circle. The second end of the rope loop 4 is suspended in the air. The top end of the support rod 7 is rotatably connected to the second end of the rope loop 4, and the bottom end of the support rod 7 is rotatably connected to the lifting rod 11. Please see Figure 10 and Figure 12 As shown, an upward spring 13 is installed inside the support beam 2, and the bottom end of the upward spring 13 is connected to the lifting rod 11. It is used to pull the lifting rod 11 to the highest position so that the tooth block 12 separates from the tooth groove 10 and the rope loop 4 is in a horizontal state. When the steel cage is placed in the steel cage placement area, the rope loop 4 is squeezed by the steel cage into a state with the second end facing down and the tooth block 12 bites the tooth groove 10.

[0020] In the initial state, the lifting rod 11 is pulled upward by the pull spring 13, so that the lifting rod 11 is at the highest position. At this time, the tooth block 12 is separated from the tooth groove 10 and the rope loop 4 is supported by the support rod 7 and is in a horizontal state.

[0021] Before placing the reinforcing cage, adjust the height of the two ends of the cable 5 fixed on the two outermost support beams 2, and press the cable 5 onto the rope support 3 using the rope pressure plate 9. This fixes the length of the cable 5 in each reinforcing cage placement area, allowing adjustment of the cable 5 length in all reinforcing cage placement areas. Therefore, after placing the reinforcing cage in the placement area, the support beams 2 on both sides of the placement area abut against the sides of the reinforcing cage, thereby using the weight of the reinforcing cage itself to clamp and fix the sides of the reinforcing cage in the placement area. This greatly improves the stability of the stacked reinforcing cages and is applicable to clamping and fixing reinforcing cages of different diameters.

[0022] During the process of placing the rebar cage into the rebar cage placement area, since the rope loop 4 is not yet in a state where the second end is vertically downward, under the pressure of the rebar cage, the second end of the rope loop 4 rotates downward continuously, causing the lifting rod 11 to continuously stretch the upper spring 13, causing the tooth block 12 to move towards the tooth groove 10. At the same time, the support beam 2 will automatically press against the side of the rebar cage until the rebar cage is completely placed into the rebar cage placement area. Then, the support beam 2 is clamped on both sides of the rebar cage, and the tooth block 12 engages with the tooth groove 10 to automatically fix the support beam 2.

[0023] Please refer to Figure 1 As shown, the length of the cable 5 between the opposite ends of the rope loops 4 on both sides of the placement area is less than half the circumference of the rebar cage, and the length of the cable 5 between the opposite ends of the rope loops 4 on both sides of the placement area is greater than half the circumference of the rebar cage. With this arrangement, after the rebar cage is completely placed on the cable 5 in the rebar cage placement area, the center height of the rebar cage is within the length range of the vertical rope loop 4, so that the rope loop 4 can be stably pressed into a vertical position by the rebar cage, thereby improving the stability of the tooth block 12 engaging with the tooth groove 10.

[0024] At this point, the insertion of the toothed block 12 into the toothed groove 10 is a top-to-bottom insertion process. Therefore, it can be set so that the toothed block 12 is already inserted into the toothed groove 10 before the rope loop 4 rotates to the second end facing downwards, and the support beam 2 is clamped on both sides of the reinforcing cage. This ensures that as the reinforcing cage descends and the rope loop 4 is in the second-end-facing state, the toothed block 12 is continuously inserted into the toothed groove 10 as the lifting rod 11 continues to descend. During this process, the support beam 2 remains stable in the length direction of the bottom beam 1, always being stably clamped on the side of the reinforcing cage.

[0025] In addition, please see Figure 6As shown, the support structure has a pair of cables 5 arranged in a front-to-back pattern on the rope bracket, and the distance between the centers of the two cables 5 is greater than the width of the top opening of the sliding groove 8. This arrangement provides more stable support for the reinforcing cage, reducing its swaying. Furthermore, when the diameter of the reinforcing cage reaches a certain size, allowing it to be fully placed within the placement area, the bottom of the cables 5 contacts the top of the bottom beam 1, ensuring stable support of the bottom of the cables 5 and improving the stability of the stored reinforcing cage.

[0026] Please see Figure 8 and Figure 9 As shown, a rope-pressing bolt 14 is rotatably mounted on the top of the rope pressure plate 9, and the rope-pressing bolt 14 is threaded onto the rope support 3. A sliding block 15 is fixedly installed at the bottom end of the support beam 2, and the sliding block 15 is slidably disposed in the sliding groove 8. Please refer to [link to relevant documentation]. Figure 10 and Figure 11 As shown, a lifting groove 16, which runs through the support beam 2, is provided at the bottom end of the sliding block 15. The lifting rod 11, the toothed block 12, and the pull spring 13 are all installed in the lifting groove 16. With this arrangement, the height of the rope pressure block can be adjusted by rotating the rope pressure bolt 14, thereby adjusting the rope pressure block to tighten or loosen the cable 5.

[0027] The rope loop 4 has a notch 17 on the side facing the reinforcing cage, and the cable 5 is exposed through the notch 17. The side of the rope loop 4 opposite to the notch 17 is flat, and when the second end of the rope loop 4 is vertically downward, the side of the rope loop 4 opposite to the notch 17 contacts the side of the support beam 2. With this arrangement, while the rope loop 4 is in contact with the side of the support beam 2, the reinforcing cage presses down on the exposed surface of the cable 5 inside the rope loop 4. At this time, under its own weight, the reinforcing cage, together with the support beam 2 and the rope loop 4, has a compressive effect on the cable 5, which can better prevent the cable 5 from being pulled out accidentally, and further improve the stability of the stored reinforcing cage.

[0028] Please see Figure 8 and Figure 9 As shown, arc-shaped grooves 18 are provided on the inner walls of both sides of the rope groove 6, and arc-shaped sliders 19 are provided on both sides of the first end of the rope loop 4. When both sides of the rope loop 4 are in a horizontal state, the opposite ends of the arc-shaped sliders 19 on the two rope loops 4 are in contact. With this arrangement, the arc-shaped sliders 19 are located outside the range of the cable 5, and will not be disturbed by the cable 5 when the rope loop 4 is making circular motion.

[0029] Please refer to Figures 4 to 7 , Figure 14 and Figure 15As shown, arc-shaped guide rails 20 are fixedly installed at both the front and rear ends of the rope support 3. Arc-shaped guide blocks 21 are slidably arranged on both the left and right sides of the arc-shaped guide rails 20. A toothed sleeve 22 is fixedly installed on one side of the arc-shaped guide block 21. A side pressure rod 23 is fixedly installed on the outer end of the toothed sleeve 22. A ratchet 24 is slidably inserted into the inner end of the toothed sleeve 22. An internal pressure spring 25 is connected between the inner top wall of the toothed sleeve 22 and the top of the ratchet 24. Incomplete ratchet wheels 26 are provided on both the front and rear sides of the rope support 3. The teeth on both sides face opposite directions. The two side pressure rods 23 located on the same side in the left and right directions of the rope support 3 are fixedly connected by the synchronous rod 27. The tooth sleeve 22 is connected to a liftable elastic telescopic rod 28. When the rebar cage is placed in the rebar cage placement area, the elastic telescopic rod 28 applies a downward pulling force to the rope sleeve 4. When the rebar cage placement area is in an idle state, the elastic telescopic rod 28 is in a free length state and the side pressure rod 23 is in a vertical upward state so as to be located outside the range of the rebar cage placement area.

[0030] Specifically, please refer to Figure 2 , Figure 3 and Figure 13 As shown, the front and rear surfaces of the rope support 3 are respectively arranged with the corresponding arc-shaped guide rail 20 to form a receiving area. The toothed sleeve 22 is located in the receiving area and is in contact with the opposite side of the rope support 3.

[0031] By making the above settings, when the toothed sleeve 22 is subjected to a downward pulling force, the arc-shaped guide block 21 will make a downward circular motion in the arc-shaped guide groove. At this time, the toothed sleeve 22 moves synchronously with the arc-shaped guide block 21, and the ratchet 24 can continuously pass over the teeth on the incomplete ratchet 26 through the contraction of the internal pressure spring 25. The teeth on the incomplete ratchet 26 and the ratchet 24 are set to a state that locks the toothed sleeve 22 to prevent it from making an upward circular motion. In this way, the side pressure rod 23 can be locked when it moves downward in a circular motion with the toothed sleeve 22 to any position. After the rebar cage is placed in the placement area, when the elastic telescopic rod 28 is subjected to a downward pulling force, it can drive the toothed sleeve 22 together with the side pressure rod 23 and the ratchet 24 to make a downward circular motion. When the side pressure rod 23 presses against the side of the top of the rebar cage, the side pressure rod 23 can no longer make a downward circular motion. At this time, the incomplete ratchet 26 locks the side pressure rod 23 in this position. The side pressure rod 23 has a fixing effect on the rebar cage, which further improves the stability of the rebar cage.

[0032] The ratchet 24 is in contact with the opposite side of the rope support 3. The top of the ratchet 24 is rotatably connected to the lifting bolt 29. A threaded sleeve 30 is fixedly installed on the surface of the rope support 3 above the ratchet 24, and the lifting bolt 29 is threadedly connected to the threaded sleeve 30. When the top of the ratchet 24 contacts the bottom of the threaded sleeve 30, the ratchet 24 is in a meshing state with the incomplete ratchet 26.

[0033] By making the above settings, rotating the lifting bolt 29 causes the incomplete ratchet 26 to move downward and disengage from the ratchet 24. Then, by pushing the elastic telescopic rod 28 upward, the toothed sleeve 22, together with the side pressure rod 23 and the ratchet 24, can make an upward circular motion and return to the initial state. After that, rotating the lifting bolt 29 causes the incomplete ratchet 26 to reset upward and re-engage with the ratchet 24, so as to fix the side pressure rod 23, together with the toothed sleeve 22 and the ratchet 24, in the initial state. In the initial state, the side pressure rod 23 is located outside the range of the rebar cage placement area, so as to facilitate the subsequent placement of the rebar cage to be stored into the rebar cage placement area.

[0034] Furthermore, both the front and rear surfaces of the lifting rod 11 are fixedly connected to an "L"-shaped connecting plate 31, the top of the connecting plate 31 is fixedly connected to a lifting plate 32, and the bottom ends of two elastic telescopic rods 28 located on the same side in the front and rear directions are rotatably connected to the two ends of the lifting plate 32 respectively. The top ends of the elastic telescopic rods 28 are rotatably connected to the arc-shaped guide block 21. Both the front and rear surfaces of the rope support 3 are provided with through slots 33 for the lifting of the connecting plate 31.

[0035] This design ensures that during the placement of the rebar cage into the placement area, the lifting plate 32 automatically pulls down the toothed sleeve 22 via the elastic telescopic rod 28 as it moves downwards. This causes the side pressure rod 23, the toothed sleeve 22, and the ratchet 24 to move downwards in a circular motion simultaneously, pressing the side pressure rod 23 against the side of the top of the rebar cage. Simultaneously, utilizing the elastic telescopic properties of the elastic telescopic rod 28, after the side pressure rod 23 has pressed against the side of the top of the rebar cage, the lifting rod 11 continues to descend, causing the elastic telescopic rod 28 to extend further, making the side pressure rod 23 more suitable for rebar cages of different sizes.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
